Be it known that I, THnoDon DANIELS,

"a citizen of the United States, residing :at

` Brooklyn, in the county of Kings and State Vof New York, have invented new and useful Improvements in Bookbindeis'of which the 'following is a specification.

rlhis yinvention relates to'y binders especially adapted to be used for holding books, magazines, 'periodicals or the likeand it con- 'ssts in the novel features vhereinafter described and claimed.

An object of the invention is to providea Vbinder of simple and durable structure adapted to be yeasily and quickly manipulated for the purpose of securing the books or magazines therein and which may also be readily manipulated for the purpose of releasing the books or magazines.

llith the above objectsV in view the binder comprises a casing composed of two sections hingedly connected together and having at their ends transversely disposedr` plates which overlap each other. The said sections are provided at their longitudinal edges with curls adapted to receive flexible strips of the covers of the binder the said curls also beingV adapted to receive rods whereby the strips are secured in the curls. Toggle levers are pivotally connected with the sections at their outer'ends'and are pivotally connected at their inner ends with blocks which are screw threaded upon a shaft located between the sections. threads upon the shaft at the opposite ends thereof are disposed in opposite directions and consequently as the shaft is turned the blocks are moved either toward or away from each other simultaneously.

In the accompanying drawing, Figure 1 e is a perspective view of the binder showing the manner in which a book or periodical is held in the same. Fig. 2 is a detailed plan view of the back portion of the binder in open position. Fig. 3 is 'an end Vview of the same. Fig. 4 is a transverse sectional view of the same cut on the line 4-4 of Fig. 2. Fig. is an enlarged detailed sectional view of the edge portion of one of the sections of the binder. Fig. 6 is a. detailed perspective view of parts of the binder the said parts being disconnected from each other.

The back of the ybinder comprises sections 1 which are hingedly connected together as at 2. The said sections are preferably formed from sheet metal.Y The sec- The e sgeciiicatipn of Iieaersoratentl PatentedSept. 21, 19155.

tionsl are provided .at one end with trans.- versely disposed plates 3 which overlap each other and at their opposite ends with transversely disposed platesA 4 which also overlap eachother. 4The plates 4 are provided at their inner'portions with recesses the71H object of which will be explained herein# after. e

The sections 1v are provided at their free -edges with longitudinally disposed inwardly The edges of Vthe* said directed curls 6. curls being spaced fromv the intermediate portions of the sections -as best indicated in :Fig 4 of the drawing.. A cover 7 is adapted to be applied to the back ofthe binder of which the sections 1 are components andthe cover 7 may be rigid or iiexible as desired.v

The sections 1 are provided at their inner sides with inwardly disposed knuckles 10 arranged in pairs the pairs of knuckles beingdisposed in the vicinity of the ends of the sections 1. Eye-members 11 are positioned between the members of the pairs of the knuckles and the eye membersv 11 and serve as means upon which the eye members 11 may swing with relation to the sections 1. As shown in Fig. 6 ofwthe drawing the pivot 12 is in the form of a cotter pin although it is to be understood that any other suitable form of pivot may be employed. Toggle levers or links 13 are pivotally connected at their outer ends with the eye members 11 and thek inner ends of the said levers are .90 knuckles 10 and pivots 12 are passed through pivotally connected with blocks 21. A shaft 15 passes through the blocks 21 and is Vprovided `at its opposite end portions with threads 16 the threads at the opposite end portions of the said shaft being disposed in opposite directions as best indicated in Fig. 2 of the drawing. The shaft 15 is squared at one end as at 17 and the said squared portion is located opposite the recesses 5 in the plates 4. Consequently a key (not shown) may be inserted through the said recesses and engaged with the squared portion 17 of the shaft 15 for the purpose of turning the said shaft. rlhe levers 13-are provided with slots 18 which receive a pin 19 carried by a block 20, which is screw-serted on theshaft 15. The inner ends of the leversl are pivoted to a block 21 which is slidably mounted on the shaft 15. Then the shaft 15 is turned the block 20 moves along the same and the'pinl) is carried along the slots 18, whereby the levers 13 are swung on the block 21. and thus the sections 1 are moved toward or away from each other.

From the above description taken in conjunction with the accompanying drawings it will beY seen that when the shaft 15 is turned so that the blocks 1st-are moved away from each other the toggle levers 13 are moved longitudinally and the free edge portions of the sections 1 are swung away from each other. Then the free edge portions of the said sections have been suiiiciently separated or spaced from each other the books or periodicals are inserted between the free edge portions of the sections and then byy turning the shaftA 15 to cause the blocks 14: to move toward each other the toggle levers 13 are moved longitudinally whereby the Vfree edge portions of the sections 1 are Copies of this patent may be obtained for five cents each, by addressing the Commissioner of drawn toward each other and the books or periodicals are clamped between the free edge portions of the said sections. It is apparent that when it is desired to remove a book or periodical from the binder the operation just above described is reversed. Therefore it will be seen that a binder of simple and durable structure is provided and that the parts may be easily and quickly manipulated for the purpose of securing books or periodicals in the same or for re- .moving the books 'and periodicals there- THEODOR DANELS.
